Abstract (en)

[origin: ES8506496A1] A nozzle is used to mix two or more flowable reaction components which nozzle has a force controlled injection needle (7) and a force controlled needle casing (12) guided in a guiding bore (12). One component emerges centrally into an outlet channel (3) while the opening (25,26) of at least one further supply pipe (23,24) lies in the area of a sealing surface (4) which limits one side of the guide bore (2) and which forms a tight fit (18) with an outer sealing surface (17) thereof when the needle casing (12) is in a closed position.
